Due to the recent influence of the new coronavirus (SARS-CoV-2), opportunities to improve knowledge of new medical technologies are lacking. To provide safe medical technology, we examined the medical device operation support system using smart glasses, which is a wearable device. This system enables actual operation while watching operation videos of various devices when necessary and can also provide remote technical support. By comparing the performance of multiple smart glasses, we arrived at an appropriate system that can be used in clinical practice.
